, MEANS FOR OBSERVING AND SEPARATING HEAVY OBJECTS FROM DUST-LADEN AIR-CURRENTS.

To all whom it may concern:

Be it known that I, DANIEL Fooan'ry, of

.the city of Ottawa, in the county of Carleton, Province of Ontario, Canada, have 1nvented certain new and useful Improvemerits in Means for Observing and .Separatin Heavy Objects from Dust-Laden Air-Currents, of which. the following is a specification.

My invention relates to an improved separator for vacuum cleaning apparatus and the objects of my invention are to provide an exceedingly cheap and simple device connected with the nozzle, which will prevent the entry of any solid articles into the a-p-- para-tus, and will also serve to indicate and gage the operation thereof; and it consists essentially of a preliminary separating chamber inserted in the pipe connected to the nozzle, having a screen therein, and a glass window through which the passage of material through the separating chambermay be observed; the various parts of the device being constructed and arranged in detail as hereinafter more fully set forth and described.

In the drawi1igs,Figure 1 is a longitudinal section through the sucker and supply pipe. Fig. 2 is an enlarged view of the bottom of the nozzle proper. Fig. 3 is an enlarged top view of the separating chamber.

In the drawings like letters'of reference indicate corresponding parts in each figure. Referring to the drawings, a. is the nozzle proper of any well known type, that shownbeing triangular in form and having a face plate 1) adapted to rest on the carpet 0 or other article -being cleaned. The-nozzle is connected to a: rigid conducting pipe at l which is usually connected to a flexible con- .ductor e which is exhausted by suitable means.- Intermediate of .the length of the conductmg pipe- (1 1s mserted aseparatmg -chamber f which may be of any desirable form, and'has therein a separating screeng of sufliciently coarse mesh to permit the free passage of the dirt and dust collected, but I ,to prevent the passage of any solid articles.

the chamber. An inlet pipe 7' extends into the interior of the bulb l2, and is connected at its opposite extremity to the side of the In operation, the dirt and dustpassing through the separating chamber can be observed through the glass bulb 71., whence it can be determined whether the apparatus is operating satisfactorily or not. Also any solid articles sucked in through the nozzle will be caught on the screen g and may be removed when the glass bulb it is unscrewed. v

'hat I claim as my invention is:

1. A device of the character described. comprising a rigid section of conducting pipe, a chamber having a glass bulb therein,

a conducting pipe extending from the glass bulb into the rigid conducting p1pe,a screen in the chamber below the opening of the conducting pipe, a second 001 luctmg pipe extending from the opposite'suleot the screen. to-tlie first mentioned conducting pipe, and a stop in the rigid conducting pipe between the opening of the two pipes leadinginto the chamber.

2. An improved separator for :dust collectors comprising a chamber having T- shaped pipe coupling members connected to the bottom, one of said members opening near the bottom and one near the top, a

, screen within the chamber between the openings of the coupling members, a glass bulb secured in the side'of the chamber, opposite the end of. the. coupling member which extends near the top, a plug Z connecting the inner ends of thecouplings and conducting pipes connected to the outer ends of the couplings. 4

In Witness whereof I have hereunto set my hand in the presence of two witnesses. I

I DANIEL FOGARTY.
